-In the mounting ofthe plates in attery it -will be understoodthat as mucho :the sur-v face ofthe material as possible should, be ac 3'5 ccssible to the nctionof thejeleetrolytc`-a'nd the surfaces of I .the respective positive and.

.one another, with of course space heing left for the relative'amount of liquid. Moreover,

4o it is necessary thatthereshould he a free oir-v culation of the liquid as rWell as afreo escape [of all gases, and 'my invention in a marked degree'posscsses the-capabilities of affording the fulfillment of these conditions in a moet 45 satisfactory manner. I n the accompanying drawingsl have illustrated my invention in'one of the forms found practically efficient, andin which- Figure 1 is a perspectiveview of a. vessel or ...ula-ff; 5 de1phia,in the` lounty of Philadelphiafa'ndefe-tingcelleoutaininga serie'sof plates mountedinl betten lat 'shgnvny in' application between 6m .l gated'ius tating plate or diaphragm; and Fig. fisaftopviewgthercof,showing the plane of crrugatiomiof said'plate or dirqnnngrn.v
